Black Keys rocker Dan Auerbach has been rocked by some serious allegations.

The musician's wife has filed for divorce and, per the Huffington Post, claims in court documents that Auerbach was an abusive husband.

Stephanie Ann Gonis Auerbach did not disclose the exact nature of the abuse that purportedly occurred, but she alleges that it led, in one instance, to an incident in which she supposedly cut herself "superficially" on her legs and ankles.

At the Grammys last February, the Black Keys scored big, taking home four awards: Best Rock Performance and Best Rock Song for "Lonely Boy" and Best Rock Album for El Camino, while Auerbach himself snagged the award for Producer of the Year.

Coming into the night, the rockers had dominated the field with six nominations, including Album of the Year.
